Rimless or Hooded tank
I really like the look of rimless tanks with hanging lights but I don't know anything about them. I looking in to a 100-120 gal. It seem like it would be hard to keep the water clean for stuff falling in. Does anyone have any suggestions and what are some pros and cons

You could try a custom glass/acrylic top to sit on top, so it wouldn't be too obtrusive. IME, having no lid whatsoever requires very frequent top-offs, as the evaporation is crazy.

I have no lid on any of my tanks.. no issues with evap, dust, dirt, etc. Makes cleaning and feeding much easier, and just looks better IMO. Glass/plastic lids tend to get foggy after a short time IME

fort384 02-01-2011 07:17 PM

I don't use lids on any of my tanks either, fwiw. Concur with mfd...

mr_X 02-01-2011 07:26 PM

rimless is the way to go if you can afford it!
hang the fixture from the ceiling and go topless. it will look fantastic. yeah, nothing "falls in" unexpectedly, unless your ceiling is falling in on a regular basis!

It also helps with gas exchange... I had an issue with glass lids on my 150g when I first started it up. The lack of oxygen exchange caused my pH to crash.

Badfishofbabylon 02-01-2011 08:22 PM

I mention like particles in the air, also I have a bull dog who shed little white hairs like crazy so i would worry about white hair all over the tank

Badfishofbabylon 02-01-2011 08:24 PM

What about salt forming on you walls or anything, kind like it does on the inside of glass lids and lights

I don't know about salt, because I only do freshwater, but I have some sort of.. stuff on my wall behind my open-top tank, lol. I don't personally know what it's from, but it's there.

mr_X 02-02-2011 12:02 AM

i've always had open top tanks, and i've not seen anything out of the ordinary in the way of salt creep all over, except in instances of excessive bubbles or turbulent water flow.

Badfishofbabylon 02-02-2011 12:06 AM

What about the life tank? Do the seems leak easier? And is 90 gal too big for rimless?

mudraker 02-02-2011 12:06 AM

I have two large dogs and five cats, some with long hair, that sleep in the same bedroom as my five tanks, three are topless. There are no issues.

mr_X 02-02-2011 12:07 AM

no, you can get pretty much any size home tank in rimless.

Badfishofbabylon 02-02-2011 12:09 AM

Well I think I'm going to go rimless. Now I just have to decide on what type of lights...

mr_X 02-02-2011 12:13 AM

where are you located? i know a good company that makes tanks to specs.

Badfishofbabylon 02-02-2011 12:16 AM

Michigan, just moved back 2 months ago from Cali. Miss the fish stores out there

mr_X 02-02-2011 12:22 AM

well, then check out glass cages. they are the cheapest, and they are from ohio if i remember correctly.

Badfishofbabylon 02-02-2011 12:38 AM

Yeah thats who I was looking at

cabezon 02-02-2011 12:45 AM

Oh god, here it comes. In our local club mentioning glass cages. Is like putting a tang in a biocube

Badfishofbabylon 02-02-2011 06:48 AM

Why? Are they no good or something?

mr_X 02-02-2011 10:05 AM

they generally are hit or miss. reports of sloppy silicone and other things are not uncommon. i had pretty good luck with them. they made my 195.
the thing you have to ask yourself is- are the blemishes worth the better price?

when i went to pick up my tank many others were too. it was at a centralized location about an hour from my home.
my tank had a small nick on the corner back of the tank and it was supposed to be euro braced. instead this is what i arrived to find-

they also put that black plastic border on the tank to hide sloppy craftsmanship. i complained to the people in charge and they handed me a few dollars cash right there. i accepted it because i was on a schedule. if i didn't have a tank that weekend, i would have had to pay for another month at my old apartment...bla bla bla...
anyway, this tank was about half the price of the other quotes i got.

it was worth it to me, and i would use them again if they were able to duplicate another "half price" deal like that.

Badfishofbabylon 02-02-2011 10:27 AM

Was the black boarder removable and just used for shipping? Did you just buy the tank or did you get the sump and stand too? I feel like I could make a sump for less than they charge

mr_X 02-02-2011 10:29 AM

that's not removable. it's siliconed on. it wasn't horrible. maybe if i was displaying this tank differently, i would have been angry, but it was meant for an in-wall application and wouldn't have been seen by anyone but me-

Badfishofbabylon 02-02-2011 10:31 AM

Did you order it rimless?

Badfishofbabylon 02-02-2011 10:35 AM

This is the look of the tank I hope to get

mr_X 02-02-2011 11:36 AM

a rimless peninsula. very cool.
no, i ordered it euro braced. it's not supposed to have any braces across the top. i was hoping to light it with 2 x 400 watt halides in lumenarc reflectors, but when it came light that, i went with 3 x 250 watt biggy.

Badfishofbabylon 02-02-2011 11:44 AM

How are the Halides on your electricity bill? I'm think about getting hanging one for the tank instead of going with T5s, but I know nothing about them

mr_X 02-02-2011 11:51 AM

well, it's all relative. a 250 watt halide uses 250 watts of electric. it will only light a roughly 24" x 24" area. if you are considering a tank like the one pictured above, then a single 250 or 400 watt halide might be your best choice.
if you end up with a rectangular shape, you might need 2 of them for complete coverage and then you would weigh out your options-
besides aesthetics, you might be better off with a t-5 unit, because you can light a 4' area with less watts used.
you are going to have to evaluate your situation and go with what works best.
personally, if i had that tank you posted, i would use a single 400 watt halide in a lumenbright pendant.
Lumen Bright 3 SE Mogul Base PENDANT by CoralVue* - AquaCave
the reflector inside that pendant is supposed to be the best on the market.

Badfishofbabylon 02-02-2011 12:07 PM

Nice link! Is this a complete light fixture or just the housing

mr_X 02-02-2011 01:55 PM

that's just the pendant itself. you would need a bulb and ballast.

Badfishofbabylon 02-02-2011 02:38 PM

What about one or 2 of these

mr_X 02-02-2011 07:42 PM

well, what tank are we talking about? the peninsula in the photo you posted? it's going to take 2 of those smaller pendants for the right coverage, and i'm sure those pendants don't have the intensity that the lumen brights do.

if it was me, i'd go with the best i could get. i believe that lumenbright to be the best metal halide pendant available.

Badfishofbabylon 02-02-2011 10:46 PM

Got yah. What about those MH and T5 combo lights

mr_X 02-03-2011 05:36 PM

well, again, it depends on what tank you end up with. first pick the tank, and then pick the light.
